Background:. The risk of women developing breast cancer after augmentation mammaplasty may be lower than the general population, with minimal current literature on breast reconstruction in this population. We sought to evaluate the impact of previous augmentation on postmastectomy breast reconstruction. Methods:. Retrospective review of patients who underwent mastectomies from 2017 to 2021 at our institution was performed. Analysis included frequencies and percentages, descriptive statistics, chi-square analysis, and Fisher exact test. Results:. Four hundred seventy patients were included, with average body mass index of 29.1 kg/m2, 96% identifying as White, and an average age at diagnosis of 59.3 years. Twenty (4.2%) patients had a prior breast augmentation. Reconstruction was performed in 80% of the previously augmented patients compared to 49.9% of nonaugmented patients (P = 0.01). Reconstruction was alloplastic in 100% of augmented and 88.7% of nonaugmented patients (P = 0.15). All reconstructed augmented patients underwent immediate reconstruction compared with 90.5% of nonaugmented patients (P = 0.37), and two-stage reconstruction was most common (75.0% versus 63.5%; P = 0.42). Of the previously augmented patients, 87.5% increased implant volume, 75% underwent same implant plane reconstruction, and 68.75% underwent same implant-type reconstruction as their augmentation. Conclusions:. Previously augmented patients were more likely to undergo reconstruction after mastectomy at our institution. All reconstructed augmented patients underwent alloplastic reconstruction, with most performed immediately in staged fashion. Most patients favored silicone implants and maintained the same implant type and plane of reconstruction, with increased implant volume. Larger studies are required to further investigate these trends.
